The proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. Therefore, the proximity sensor 141 has a considerably longer life than the contact sensor, and its utilization is also considerably higher.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

To explain an example of the operation principle of the high frequency oscillation type proximity sensor, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface in the state of oscillating the high frequency wave of the wave in the oscillation circuit. This change is converted into an electrical signal to detect the presence or absence of a sensing object. Therefore, even if a non-metallic material comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

Even if the proximity sensor 141 is not firmly mounted, when the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the pointer by a change in an electric field according to the proximity of the pointer.

Therefore, when the pointer is located in close proximity to the touch screen although it is not actually touched, the position of the pointer and the distance between the pointer and the touch screen may be detected. Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized on the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the pointer on the touch screen is referred to as "proximity touch". The act of actually contacting will be referred to as "contact touch". In addition, the position of the proximity touch with the pointer on the touch screen refers to a position where the pointer is perpendicular to the touch screen when the pointer is in proximity touch.

The proximity sensor 141 detects a proximity touch and a proximity touch pattern (for example, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, and proximity touch movement state). According to the detected proximity touch operation and the proximity touch pattern, corresponding information may be output on the touch screen.

The sound output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like. In addition, the sound output module 152 outputs a sound signal related to a function (eg, a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying occurrence of an event of the mobile terminal 100. Examples of events occurring in the mobile terminal include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than an audio signal or a video signal. For example, the signal may be output in the form of vibration. When a call signal is received or a message is received, the alarm unit 153 may output a vibration to inform this. Alternatively, when a key signal is input, the alarm unit 153 may output a vibration in response to the key signal input. Through the vibration output as described above, the user can recognize the occurrence of the event. Of course, the signal for event occurrence notification may be output through the display unit 151 or the sound output module 152.

The memory 160 may store a program for processing and controlling the controller 180 and may provide a function for temporarily storing input / output data (for example, a phone book, a message, a still image, a video, etc.). It can also be done. In addition, the memory 160 may store data on vibration and sound of various patterns output when a touch input on the touch screen is performed.

Hereinafter, a method of transmitting an image to a counterpart terminal in a mobile terminal according to an embodiment of the present invention will be described.

The controller 180 of the mobile terminal 100 controls the camera 121 to capture an image, and stores the captured image in the memory 160. In this case, the controller 180 compares the photographed image with photo information (face information) stored in the phone book using an image comparison engine. That is, the controller 180 searches for phonebook information including photo information (personal information and face information) that matches the captured image among the phonebook information. The phone book information includes a name, a phone number, a device address (BD_ADDRESS), an e-mail, an address, and the like.

In addition, the controller 180 drives the short-range communication module 114 to perform short-range communication when the matching phone book information is found, and establishes a connection for communication with the counterpart terminal based on the searched phone book information. The controller 180 transmits the captured image to the connected counterpart terminal.

According to a user input, the controller 180 executes the phone book function and displays an input screen for adding a phone number on the display unit 151. The user may input desired information on the input screen. Here, when the user selects the photo information input according to a predetermined procedure, the controller 180 drives the camera 121. When photographing the opponent through the driven camera 121, the controller 180 stores the photographed image and displays the photographed information in the area where the photo information is displayed.

Then, when a storage command is input by the user, the controller 180 stores the input information in the phone book. Names and / or photo information among the items stored in the phone book are used to search for the device address of the terminal to which the captured image is to be transmitted.

6 is a flowchart illustrating a data transmission method of a mobile terminal according to an embodiment of the present invention.

First, the controller 180 drives the camera 121 according to a user input and displays a photographing screen on the display unit 151. When a photographing command is input from the user input unit 130 on the photographing screen, the controller 180 photographs a subject (image) detected through the camera 121 (S101).

Subsequently, the controller 180 temporarily stores the photographed image in the memory 160 and compares the photographed image with previously stored phone book information (S103). That is, the controller 180 searches for photo information (face information) of the phone book information that matches the person information (face information) included in the captured image by a predetermined ratio or more. For example, the face information is extracted from the photographed image, and the extracted face information and the face information of the phone book information are compared to search for phone book information including face information that matches a predetermined ratio or more. Here, the predetermined ratio may be set to a default value or may be set by a user's menu operation.

If there is information that matches the captured image, the controller 180 establishes a connection with the counterpart terminal based on the corresponding phonebook information (S105 and S107). That is, when the phone book information of the same person as the person included in the captured image is found, the controller 180 drives the short range communication module 114 and uses the device address included in the retrieved phone book information to select the corresponding terminal. Search and establish a connection.

When the connection setting is completed, the controller 180 transmits the captured image to the counterpart terminal through the short range communication module 114 (S109). Here, the short range communication module 114 may be implemented as a Bluetooth device.

On the other hand, if there is no matching information in the step (S105), the controller 180 stores the captured image in the memory 160 and converts the screen of the display unit 151 to a photographing screen (S111). In addition, the controller 180 adds the captured image to the camera album list.

FIG. 7 is an exemplary diagram illustrating an example of transmitting an image captured by a mobile terminal according to an exemplary embodiment of FIG. 6.

First, when a camera function is selected by a user's menu operation, the controller 180 drives the camera 121 and displays a photographing screen on the display unit 151. Thereafter, when a photographing command is input through the user input unit 130, the controller 180 controls the camera 121 to capture an image. In this case, the controller 180 displays the captured image on the display unit 151 as a preview screen.

When a transmission command is input on the preview screen, the controller 180 searches for the same person information in the phone book that matches the person information of the photographed image. In the present embodiment, the preview screen is displayed and the information corresponding to the captured image is searched when the transfer command is input from the displayed preview screen. The search operation can be implemented. For example, when automatic transmission is set by the user's menu setting, the controller 180 may automatically perform the search operation when a photographing operation is performed without inputting a transmission command.

When the phone book information including the same person information is found as a result of the search, the controller 180 establishes a communication environment with the counterpart terminal based on the retrieved phone book information. When the communication environment setting is completed, the controller 180 transmits the captured image to the counterpart terminal. At this time, the controller 180 displays a message indicating the progress and status in a pop-up form so that the user can grasp the progress.

Alternatively, the controller 180 may perform the shooting by displaying a status icon on the shooting screen without displaying the progress status as a message, and may allow the user to check the progress status through the status icon.

First, the controller 180 drives the camera 121 and displays a photographing screen on a display screen. When a photographing command is input through the user input unit 130 while the photographing screen is displayed, the controller 180 photographs an image through the camera 121 (S201). That is, if the user manipulates the camera 121 toward the subject in which the subject is desired to be photographed and then presses the shutter, the controller 180 photographs the subject detected by the camera 121.

When the image capturing is completed, the controller 180 stores the captured image (S203). In this case, the controller 180 may display the captured image as a preview screen so that the user can check it. In addition, the controller 180 may implement a user to directly input a file name when storing the photographed image. Therefore, the user may set the file name to a word associated with the captured image.

When the captured image is stored, the controller 180 compares the file name of the stored image with name information of the phone book (S205). That is, the controller 180 searches for phonebook information including name information at least partially matching the file name of the stored image. Here, the control unit 180 searches for the name information of the phone book information in which at least one syllable matches the file name.

As a result of the comparison, if there is the phone book information that matches the file name of the stored image, the controller 180 establishes a connection with the counterpart terminal based on the corresponding phone book information (S207, S209). Here, the controller 180 drives the short range communication module 114 and attempts to establish a connection with the counterpart terminal using the device address included in the phonebook information.

When the connection with the counterpart terminal is established, the controller 180 transmits the captured image to the counterpart terminal through the short range communication module 114 (S211).

On the other hand, if the information that matches the file name does not exist (not retrieved) in step S207, the controller 180 switches to the photographing screen.

When the image is captured by the camera 121, the controller 180 displays the image acquired through the camera 121 on the preview screen. After displaying the captured image on the preview screen and a storage command is input, the controller 180 displays an input window for inputting a file name of the captured image.

If a confirmation command is input after a file name is input to the displayed input window, the controller 180 stores the captured image in the memory 160 under the input file name. In addition, the controller 180 adds the file name of the stored image to the camera album list.

When the storing of the captured image is completed, the controller 180 searches for the stored phonebook for phonebook information matching the file name of the stored image. The controller 180 displays the searched result on the display screen. That is, the controller 180 compares the file name with name information included in the phone book information, searches for name information that matches at least a portion of the file name, and displays the search result.

For example, when NAM and HYUN take a picture together with a mobile terminal of HYUN and store the taken picture under a file name of 'NAM AND HYUN', the controller 180 is a phone book in which part of the file name coincides with the file name. Retrieve information. Then, the retrieved information NAM, YOUNG-NAM, NAMSU is displayed on the display screen.

When one of the displayed search results is selected, the controller 180 establishes a connection for short-range communication with the counterpart terminal based on phonebook information corresponding to the corresponding item. When the connection setting is completed, the controller transmits the captured image to the counterpart terminal. For example, when the NAM is selected from the search results, the controller 180 establishes a connection with the terminal of the device address corresponding to the NAM. That is, the mobile terminal establishes a connection with the terminal of the NAM. The controller 180 transmits the captured image to the terminal of the NAM.
